Oh my goodness. One of the best Kdramas I had the immense pleasure of watching.
It has everything a good story, a great atmosphere, good romance, great family moments, engaging episodes and a really good end to wrap it all off.
Such a satisfying ending truly. I love the fantasy elements, the supporting cast and especially the Main Characters and every scene they interacted with each other.
All the episodic cases are also both heartwarming and heartbreaking and the best part is how our MCs help these people move on or get their happiness, give them the push they need all the while relating to them and reveal a bit of the backstory related to those cases.
Truly well written. The Villain is good enough too.
Grim Reaper Chief is also a great supporting cast.

All in all Highly recommended if you like Fantasy, episodic cases, Found Family, Slice of type romance and happy endings. Get ready though to grab a couple of tissues to cry a little from both sadness and ultimately happiness.
